Description

An intelligent electrocardiogram blood pressure instrument

technical field

The present application relates to the technical field of medical monitoring, in particular to an intelligent electrocardiograph and blood pressure instrument.

Background technique

Hypertension with arrhythmia is a common phenomenon in medicine, especially with paroxysmal arrhythmia. It is a common clinical phenomenon that arrhythmia must be accompanied by changes in blood pressure, but the ECG of arrhythmia cannot be obtained at the same time when blood pressure is measured, and the blood pressure cannot be obtained at the same time when ECG is done. Paroxysmal arrhythmia is common disease, frequently-occurring disease. Especially for patients with chronic diseases outside the hospital, it is not uncommon to see health and sub-health.

Diagnosis of arrhythmia is mostly based on electrocardiogram. An EKG can only be done in a medical facility. It is impossible to record paroxysmal arrhythmia when you go to the hospital for an electrocardiogram. Changes in arrhythmia and blood pressure cannot truly reflect the disease at that time when you go to a medical institution for treatment. Doctors cannot diagnose arrhythmia and blood pressure changes in patients outside the hospital, so that patients cannot receive correct diagnosis and treatment. Because patients often cannot measure ECG, blood pressure and other data in real time outside the hospital or at home, it is because patients cannot tell the condition of paroxysmal arrhythmia when they seek medical treatment, and doctors cannot judge the condition at the time of onset, which brings great difficulties to doctors' diagnosis and treatment. difficulty.

Existing sphygmomanometers and electrocardiographs have single functions. The sphygmomanometer can only measure blood pressure and pulse rate data, but cannot obtain the electrocardiogram of arrhythmia. The electrocardiograph can only measure ECG, and cannot obtain blood pressure data at the same time. Neither a sphygmomanometer nor an EKG machine can measure real-time data on heart rhythm, heart rate, and blood pressure. Some existing measurement equipment cannot intelligently judge, save, and upload data such as blood pressure, ECG, and arrhythmia to the network patient health management service platform after measurement. Real-time measurement data of blood pressure, heart rate, and arrhythmia ECG when paroxysmal arrhythmia occurs outside the hospital or at home are permanently stored on the patient health service platform, providing evidence for doctors to diagnose and treat patients' diseases, and reducing misdiagnosis and mistreatment.

The invention patent with publication number CN1293943A discloses an ambulatory sphygmomanometer and its measuring method. The ambulatory sphygmomanometer can automatically and continuously measure blood pressure without an inflatable device. The body of the ambulatory sphygmomanometer processes and analyzes the two-way signal input of the chest ECG signal and the fingertip pulse signal, measures the relative transmission time of the two signals with the R-wave trigger mode of the ECG signal, and determines the blood pressure value according to the transmission time. The ambulatory sphygmomanometer cannot measure ECG and heart rhythm data, nor can it permanently store the measured data through the health service platform to provide data for doctors to diagnose and treat patients.

The utility model with authorized notification number CN204394493U discloses an intelligent sphygmomanometer, whose physiological parameter acquisition module includes an electrocardiographic signal acquisition module, a body temperature signal acquisition module and a pulse signal acquisition module. It realizes continuous ambulatory blood pressure measurement and automatic detection of pulse pressure signal, but cannot realize ECG and heart rhythm data measurement, and cannot permanently save the measurement results to the patient health service platform.

The invention patent with publication number CN105662373A discloses an intelligent heart rate, heart rate, electrocardiograph, and blood pressure monitor, which solves the above-mentioned inability to permanently save the measurement results to the patient health service platform; however, the impact of the environment on the patient's measurement results and data collection are not considered during the measurement process Influences such as data distortion caused by noise in the process.
